Product Description

The Sigma 105mm f2.8 EX Macro delivers superb, distortion-free images throughout its broad focus range, from infinity telephoto to 1: 1 (life-size) macro, as close as 12.3" without accessories. Its non-rotating front lens group makes it easier to work with polarizing filters and has a focus limiter.A "focus-free" mechanical design allows the lens to auto focus without any interference from the manual focus ring. This makes it easier to hold the lens without affecting the speed or normal operation of the autofocus function. Rugged mechanical construction also makes it durable enough for even the heaviest use required by professional photographers.The Sigma 105mm f2.8 EX Macro features the new deluxe external EX finish. These features and other Sigma optical advances, including an uncommonly broad range of focus, make this an ideal lens for a wide variety of applications, from nature photography to portraits. A handy screw-in type metal sunshade makes it easier to rotate a polarizing filter.

Amazon.com Product Description

Optimized for Nikon digital SLR cameras but also compatible with film SLR cameras, the Sigma 105mm f/2.8 medium telephoto lens allows a greater working distance between the lens and the subject, helping it excel in all shooting ranges. The increased working distance of the lens is ideal when taking the picture of a flower among several branches, or an insect on a leaf. The narrow angle of view helps simplify the background, while the shallow depth of field makes it easier to handle the composition. The lens also offers a super multi coating that reduces the flare and ghosting that tends to occur when using digital SLR cameras, helping create crisper, sharper photos. And thanks to the Dual Focus (DF) system, the lens is easy to hold during autofocusing, but also offers smooth and positive action should you choose to focus manually on images. Other features include a minimum aperture of f/32, a screw-in lens hood that supports the use of circular polarizing filters, and a minimum focusing distance of 12.3 inches. Offering a 35mm equivalent field of view of 178mm on a digital SLR camera, the lens carries a one-year warranty.

 "If you are thinking about getting it; GET IT!" 2009-12-23
By Jeremy D. Catchings (Texas)
I have had this lens for more than a year so I know all the Pros and Cons; I did not just buy it and I am not writing a spur of the moment review. If you are debating between this lens and the Nikon one, I would go with this one. I am not saying this one in better than the Nikon because I haven't used the Nikon, but I don't imagine it is $350 better.



Now there are reviews that complain about the auto-focusing on this lens. It is a Macro lens meaning its field of focus is very small at 2.8 so it will tend to go back and forth at times, especially if there is a lot of things in the viewfinder. If you know how to use a DSLR then should be able to Manual Focus it. When shooting portrait style photos I have no problem with the autofocus, now with nature it doesn't always want to focus perfectly no, but like I said above it is a Macro lens and focuses very tight. Also a one person said to go to Manual Focus you have to flip the switch on the camera, one the lens, and move the focusing ring. Which is not true. The switch on the lens is a focus limiting switch. Which locks the camera in full minimum focus ratio, meaning it will focus closer up, or you can limit it.



I personally don't like the lens hood because it screws on, instead of twist and lock, which also means you can't put a filter on the lens directly while using the lens hood. Instead you have to put the filter on the hood itself.

Also it fits the Nikon but doesn't lock in the camera body as easy or smoothly, again it still fits and works fine.



I personally love my sigma lens and will definitely buy my next lens through Sigma. Most likely will be the 50mm Macro.

 "Buy this. Do it nao." 2009-09-30
By Chad P. Vincent (New Jersey, USA)
I won't lie. I know nothing about macro photography other than I want to learn how to do it and do it well. So I read around and a lot of people said this was a very solid lens to go with. More importantly, though, I spent hours looking at photos taken with this lens on the exact body that I use. I liked what I saw, the price was reasonable, so I went with it. When it came I didn't even read any of the fine literature that comes with it, I just put it on and started shooting pepsi cans, keyboards, and creepy collections of Hummels my mom has. They immediately looked awesome, thats without modifying any settings. I'm sure I have no idea what I'm doing and yet I took some photos that look sweet. I suppose the one thing I will say is that when you auto focus it is a bit noisy, but I was alone in my room with no noise at midnight. Under any other circumstances I am confident it will not be noticable. and honestly even if it is, is that really a reason to not by an otherwise quality lens? (the answer is no.)



get this nao.

 "Excellent performance lens" 2009-09-11
By angbrey (ny)
From life-size close-up to infinity, from 35mm to digital, this lens provides superb, sharp and distortion free images. I would highly recommend this lens to be added to your camera bag. It delivers clear crisp images at normal focusing ranges while providing high image quality. And at life sized magnifications, you receive a realistic impression of your subjects.

 "After using this lens I'd rate it so,so" 2009-09-01
By K. Kimberly (Martinez, Ga USA)
I was very pleased at first with this lens,however after about a month I have found myself becoming Very frustrated with the slow,noisy, and sometime non-existent auto-focus ability and the extremely "touchy" manual focus mode means that you better not be in a hurry to get your shot because you're gonna be fidgeting for awhile trying to get the focus indicator to light up..... on a Sony A300 anyway. I have 2 other Sigma lenes, a 28mm and a 70-300mm, and couldn't be happier with their performance,I suppose this is why I feel somewhat disappointed with this one.

 "Great macro/portrait lens" 2009-06-10
By Laurentiu Cristofor
I was looking for a prime lens with macro capability and since I already had the Pentax 50mm f/1.4, I needed something in the 100mm range. There were two options: this Sigma and the Pentax equivalent that was slightly more expensive. I've seen some great recommendations for the Sigma on photo.net, so I decided to go with it and I don't regret that choice. If you've been using cheaper lenses, this lens will show you why it's worth investing more into a good prime lens. I've been using it for macro photography (flowers) and for portraits with great results. I also recommend the Sigma DG 58mm Multi-Coated UV Filter to go with it.
